Ours, so discount accordingly - but this is the part we built deliberately.
Native iOS and Android apps alongside the browser version, all on one account and one world. Push notifications for timers and events on both platforms, so the game tells you when there is something to do rather than the other way round. The interface was designed for a phone first and scales up to desktop, rather than the usual arrangement in reverse.
The game itself is a mafia RPG: 100 crimes across 10 city districts with mastery progression, 100 careers from level 10 to 200, stat-driven PvP where wins take cash and losses mean a hospital cooldown, a player-run market, families with territory and rackets, racing, smuggling, heists and a seasonal arena.
Free to start, and you can try it in this browser before installing anything.
